Description

A kind of folding bicycle

Technical field

This utility model relates to bicycle, particularly to a kind of folding bicycle.

Background technology

Energy-saving and emission-reduction are all being advocated in the whole world, and China is undisputed bicycle big country.Folding bicycle is because of it Easy to carry, to take up an area space little, it has also become a very important kind in bicycle, and have and increasingly flow The trend of row.It is complicated to there is structure in current existing folding bicycle great majority, the mobile inconvenience after folding Etc. problem, the volume after simultaneously folding there is also the space of compression further.

Utility model content

It is the least that this utility model aims to provide a kind of volume after folding, and it is accommodating to fold pusher, ties simultaneously The folding bicycle that structure is simple, easily fabricated.

This utility model is achieved in that a kind of folding bicycle, including bicycle beam and bicycle beam joint, vertical tube and Vertical pipe joint, the hinge of described bicycle beam joint is that horizontal cross is arranged on the downside of described bicycle beam joint, bicycle beam joint Upside is provided with handle；Sliding seat bar upper end connects saddle；Back vent is provided with clamping device；Head tube is provided with rolling Wheel.

In handle bar folding state, the end of handlebar clamped by described clamping device.

Described clamping device is buckled for tool resilient " C " type.

Described back vent has connection sheet, and described clamping device is connected to back vent by connecting sheet.

Described roller is connected to head tube by connecting rod.

Described head tube also includes fixed block, and connecting rod front end connects roller, and connecting rod end is connected to fixed block.

Connecting rod and the hinged setting of fixed block, connecting rod can rotate in the range of 150-180 degree.

Described roller is two, and two rollers are connected to two connecting rods.

The axis parallel of said two roller is in the axial line of hinge.

The hinged heel brace that is provided with in described back vent end, described heel brace is hinged is provided with two grades of heel braces.Described two grades of feet Support and spring is set between heel brace is connected.

" C " type in this utility model buckle can secure grip fold after handlebar, prevent vehicle body from scattering and car Waving the scratching caused, very safety and simple in construction.Additionally roller is set in head tube, makes this bicycle roll over Poststack has two kinds can carry out state, meets the demand of different occasion.Two rollers can be formed with front-wheel simultaneously Effective support, it is possible to stably stand, it is simple to deposit and too many space need not be occupied, be very suitable for bringing public affairs Hand over or subway.

Detailed description of the invention

Below in conjunction with Fig. 1 to Fig. 9, this utility model folding bicycle is described in further details.

As shown in Figure 1, 2, being this utility model folding bicycle expansion schematic diagram at riding condition, it has Bicycle beam 1, is provided with bicycle beam joint 2 in the middle part of bicycle beam 1, the hinge 21 of this bicycle beam joint 2 is arranged at institute in horizontal cross State on the downside of bicycle beam joint, on the upside of bicycle beam joint 2, be provided with handle 22.At riding condition, handle 22 is in fastening posture To ensure the firm of bicycle beam.This folding bicycle also has vertical tube 3 and vertical pipe joint 4, equally, at riding condition, Vertical pipe joint 4 is in closure state.Sliding seat bar 6 upper end connects saddle 61, and this sliding seat bar 6 can be along bicycle Pipe slides, thus regulates the height demand with satisfied different bicyclists of saddle 61.

As it is shown on figure 3, release handle 22, open bicycle beam joint 2, bicycle wheels is closed up；And open Vertical pipe joint 4, is folded down vertical tube 3, and after folding, vertical tube 3 and handlebar 5 are substantially flush in frame Side.Back vent 7 is provided with clamping device 71, and this clamping device 71 is buckled for tool resilient " C " type.At handlebar 5 Folded state, described clamping device 71 is clamped the end of handlebar 5, is prevented rocking of handlebar 5.Now, bicycle Two-wheeled lands simultaneously, the hand-held saddle of user 61, and the driving after can easily push folding is slided on road surface, it is possible to Climb and fall.

As shown in Figure 4, another state after folding for this utility model folding bicycle.Bicycle head tube 8 is arranged Roller 9, described roller 9 is had to be connected to head tube 8 by connecting rod 91.Described head tube 8 also has fixed block 81, connecting rod 91 front ends connect roller 9, and connecting rod 91 end is connected to fixed block 81.This roller 9 is two, and two rollers are respectively It is connected to two connecting rods 91.Now, front wheel can be landed, roller 9 be landed simultaneously, front-wheel and two Roller 9 forms gusseted, and such user holds saddle 61, it is also possible to push the bicycle after folding very easily Move ahead on road surface, or uphill, downhill etc. is all highly susceptible to operation.

As it is shown in figure 5, the top view after folding for this utility model bicycle, it can be seen that occupation of land space is little, non- The compactest.

As shown in Figure 6,7, the hinged heel brace 73 that is provided with in back vent 7 end, described heel brace 73 is hinged is provided with two grades of feet Support 74.It is connected by spring 75 between described two grades of heel braces 74 and heel brace.Two grades of heel braces 74 can extend when opening Actual effective bearing length.So, when two-wheeled lands simultaneously, it is possible not only to carry out, and can be steady Stand voluntarily without toppling over.

As shown in Figure 8,9, described connecting rod 91 and the hinged setting of fixed block 81, connecting rod 91 can be in 150-180 degree scope Interior rotation.At riding condition, connecting rod 91 down overturns, and makes connecting rod and the unlikely car front end that protrudes from of roller, protects Barrier safety；At receiving state, it is possible to first down overturn by connecting rod 91 and touch vehicle body, then carry out the overall folding of car Folded, so take less space, effectively in packaging and storage.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all Any amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, all should comprise Within protection domain of the present utility model.
